PHP Do While Loop

In this tutorial we will study about do-while loop, by default do-while loop iterates at least once irrespective of condition. Examples in this tutorial will make it more clear.

Do-While Control Structure:

Do-While loop is another type of loop which runs at least once, since this
loop checks the condition after executing the code within. We generally use
Do-While loop when the iteration must run at least once despite of the validity
of the variable. In Do-While loop we need to initialize the variable first the
coding within the loop executes and at last the this loop checks the condition.
We should change the value of the variable within the loop.
